Implementation of Adaptive Filter Structures on a Fixed Point Signal Processor for Acoustical Noise Reduction

2 ACKNOWLEDGEMENTS We would like to thank our thesis advisor Benny Sällberg (phd student) for providing us with the opportunity to work over the past six months in the Signal Processing Laboratory, Department of Electrical Engineering. We thank him for the guidance he has provided and the confidence he has shown in our work. We also thank him for the spontaneous replies from him when we had queries and providing us necessary materials when we are in need of them. We thank Analog devices for providing an evaluation chip for the thesis. We thank Benny Sällberg for providing the addon card, head sets, amplifiers required for the thesis. We would also like to thank all the members of the Signal Processing Department for their timely help and support. 3 Index Chapters page no. Abstract 1.
